问题
My animationDidStop method is not being called for some reason, initially I thought it was because the delegate was not set but having remedied that I'm still having the same problem. Any ideas? thanks in advance :)
- (void)hideInterfaceButtonClicked : (id) sender
{
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationDidStop)];
[UIView beginAnimations:@"MoveView" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationDuration:0.5];
// Move to the right
CGAffineTransform translateInterface = CGAffineTransformMakeTranslation(454,288);
// Scale
CGAffineTransform scale = CGAffineTransformMakeScale(0.20,0.20);
// Apply them to the view
self.transform = CGAffineTransformConcat(scale, translateInterface);
self.alpha = 0.0;
[UIView commitAnimations];
}
- (void)animationDidStop {
NSLog(@"Animation Has Stopped");
[[NSNotificationCenter defaultCenter] postNotificationName:@"hiddenInteraceViewNeeded" object:self]; //after MoveView finishes
}

You could achieve what you want by using the new (iOS4+) block syntax:
[UIView animateWithDuration:0.5
delay:0.0
options:UIViewAnimationCurveEaseIn
animations:^{
// Move to the right
CGAffineTransform translateInterface = CGAffineTransformMakeTranslation(454,288);
// Scale
CGAffineTransform scale = CGAffineTransformMakeScale(0.20,0.20);
// Apply them to the view
self.transform = CGAffineTransformConcat(scale, translateInterface);
self.alpha = 0.0;
} completion:^(BOOL finished) {
NSLog(@"Animation Has Stopped");
[[NSNotificationCenter defaultCenter] postNotificationName:@"hiddenInteraceViewNeeded" object:self]; //after MoveView finishes
}];
